Abstract

A cleaning device for spot-cleaning fabrics without causing fiber damage is provided. A hand-held device with a convex face comprises treatment means, such as fibers. In use, the stained fabric is moistened with a cleaning composition and the device is rolled or rocked on the stained area. The fibers mechanically dislodge the stain. The device is especially useful as a pre-spotter in a dry cleaning operation.
